Here's something I picked up off of the used market. It's a S&W Model 64 round butt with factory bobbed hammer. These appear from time to time on the J&G website and come from armored car companies and corrections departments. I paid $319 for this one.

It's heavier than the airweight Smiths and the Ruger LCR, but it has a great trigger and is a 6-shooter.

I put on the S&W "magna" grips and added a Tyler T-grip. Worn OWB with a simple cover garment, this gun carries like a champ and is a superb shooter. When looking for a snubbie, K-frame Smiths on the used market are definitely worth a look.
